- start binder before navigating from auth, mark isBinding synchronously
- overlap plex.tv resource refresh with optimistic cached-metadata connect,
reconcile tokens/membership in background once it lands
- cached endpoint probe gets a head start on the race instead of serially
blocking it
- defer phase-1 HTTPS upgrade off the splash critical path
- per-server connect progress stream for incremental splash checkmarks
- startup timing instrumentation (bind/fetch/race/connect elapsedMs)
